Thypoch Ksana 21mm f/3.5 Review: Compact Ultra-Wide Value for Full-Frame Shooters

Thypoch has unveiled the Ksana 21mm f/3.5, an ultra-wide-angle prime lens that stands out for its compact dimensions and accessible pricing. Measuring just 2.7cm in length and weighing 131g (4.6oz), this full-frame optic targets photographers seeking a discreet wide-angle solution without compromising optical quality.

The lens employs an optical formula with eight elements arranged in seven groups, including one aspherical element and two ED (Extra-low Dispersion) glass elements. This configuration aims to control chromatic aberration while maintaining edge-to-edge sharpness. Thypoch's published MTF charts indicate consistent resolution across the frame even at maximum aperture, though real-world testing will be needed to verify these claims.

Key optical characteristics include minimal distortion according to Thypoch, along with a nine-blade aperture diaphragm that produces defined sunstars when stopped down to f/4. The proprietary Epoch Coating 73 introduces a subtle amber color signature to images, though this can be neutralized through white balance adjustments during RAW processing.

Build quality features an all-aluminum construction with manual focus operation exclusively. The 0.5m minimum focusing distance and inherent depth of field at f/3.5 make zone focusing practical for street and landscape applications. The lens includes rangefinder coupling for Leica M cameras but functions on Sony E, Nikon Z, and Canon RF systems via adapters.

Positioned against competitors:

• Voigtländer's 21mm f/1.4 costs nearly double ($1,099) while being significantly larger
• Leica's 21mm f/3.4 Super-Elmar commands $3,495 with similar compact dimensions
• TTArtisan's 21mm f/1.5 offers faster speed but heavier build at $449

The Ksana 21mm f/3.5 currently retails for $549 directly from Thypoch's official store with free shipping, though international buyers should factor in potential import duties. This pricing positions it as an accessible entry point into ultra-wide photography without the bulk of zoom alternatives.

Practical considerations:

• Ideal for travel and street photographers prioritizing minimal gear weight
• Manual focus requirement suits deliberate shooting styles
• Rangefinder users gain native compatibility without adapters
• Adaptable to mirrorless systems with full electronic communication via dumb adapters

The amber tint from Epoch Coating may appeal to film simulation enthusiasts but could require correction for color-critical work. Given the optical design and compact constraints, vignetting performance at wider apertures remains an unknown factor awaiting hands-on testing.

This release expands the growing market of third-party manual focus primes that balance optical performance with portability. For photographers seeking a compact 21mm solution below $600, the Ksana warrants consideration against heavier f/1.4 alternatives and premium-branded options costing multiples of its price.
